A temp agency recently conducted a study to determine the effects of job type and sex on length of employment. Independent random samples of employees who worked in service, technology, sales, security, and labor were obtained. The length (in weeks) of each assignment was recorded. Consider the following partial ANOVA summary table.

According to a recent study, many factors affect feed intake of chickens and, therefore, egg production.13 For example, lighting, noise, and water may all affect the efficiency of poultry production. A study was conducted to determine whether the feed intake of chickens (in kg/day) is affected by flock size and/or temperature.
